[0018] As Figures 1 to 3 shown, a bridge-type multi-functional crane with fire-fighting function includes a crane main body 1 and a controller 5. The crane main body 1 has a main beam 11 and a trolley moving wheel 12 for driving the crane main body 1 to move along a track. A trolley encoder 14 and a trolley driving motor 17 are arranged on the trolley 13. Fire detectors 3 are uniformly arranged at the bottom of the main beam 11. An extinguishing agent storage tank 4 is arranged on the main beam 11. A spray barrel 2 is arranged at the bottom of the trolley 13. A plurality of storage cavities 41 are arranged inside the extinguishing agent storage tank 4. Different types of extinguishing agents are stored inside the plurality of storage cavities 41. The storage cavities 41 are all connected to the spray barrel 2 through pipelines 42. Electric control valves 43 are arranged on the pipelines 42 between the storage cavities 41 and the spray barrel 2. The fire detectors 3, the electric control valves 43, the trolley encoder 14, the trolley driving motor 17, the trolley encoder 14 and the trolley driving motor 17 are all connected to the controller 5. In this embodiment, a plurality of storage areas are divided inside the warehouse along the moving direction of the crane main body 1. Different storage areas are used to store items of different materials or types. The storage area where the crane main body 1 is located can be identified by the trolley encoder 14 to identify the position of the trolley moving wheel 12. When the trolley moving wheel 12 drives the crane main body 1 to move, the fire detectors 3 under the main beam 11 can identify whether a fire has occurred to the items below it. When the fire detectors 3 detect a fire, first obtain the storage area where the crane main body 1 is located. According to the types of items stored in this area, connect the corresponding extinguishing agent storage cavity 41, so that the extinguishing agent is sprayed out from the spray barrel 2, and the appropriate extinguishing agent can be selected to extinguish the fire according to the fires occurring to different types of items, timely control the fire situation and reduce losses. Among them, there is a certain pressure inside the storage cavity 41.
